17.5 2108 Encoder1signalVpp V FLOAT 1.0 0.8 1.2 ERWZ FVS
Setting of the encoder signal peak-to-peak voltage value. Incremental sinusoidal encoders and absolute SinCos
encoders normally produce signals with a peak-to-peak voltage of 1 Vpp. Due to voltage drops along the cable, the
signal may have a lower peak-to-peak voltage when it reaches the feedback card, triggering the Speedfbkloss
alarm.
This parameter is used to congure the value of the peak-to-peak voltage of the incremental sinusoidal encoders
and absolute SinCos encoders on the input terminals of the feedback card.

17.6 2110 Encoder1signalcheck ENUM Check A-B 0 1 ERWZ FVS
Conguration of which channels of the incremental digital encoder must be controlled for processing the Speedfbk
loss[22].
0 Check disabled
1 Check A-B
2 Check A-B-Z
4 Check A-B-SE
If set to 1, the application checks for the presence of the signals of channels A-B
If set to 2, the application checks for the presence of the signals of channels A-B-Z
If set to 4, the application controls loss of feedback for SE (single ended) encoders.
If the application detects the absence of feedback the Speedfbkloss[22] is generated.
As loss of feedback cannot be detected at speeds of around zero, the control is only performed if the speed refer-
ence is higher than the value set in parameter 4564SpdFbkLossthreshold. It is also important to consider the fact
that when working with a speed reference slightly above the limit set in parameter 4564SpdFbkLossthreshold, the
speed error could exceed the set threshold, given the load or current limit, and generate false alarms.
In that case increase the value of parameter 4550SpdRefLossthreshold or of parameter 4554SpdRefLosshold-
off.

17.7 2112 Encoder1SSIbits ENUM 25 13 25 ERWZ FVS
Setting of the length of the SSI package, dened as the number of clock cycles, as the absolute SSI encoders on the
market have package lengths varying from 13 to 25 bits.

17.8 2130 Encoder1direction ENUM Not inverted 0 1 RWZ FVS
Selection of the encoder direction
0 Not inverted
1 Inverted
By setting 0 the encoder feedback signals are not inverted.
By setting 1 the encoder feedback signals are inverted.
